Decided to make a separate post for this as this is still available and the previous post still shows expired which is not true. Has been available before. Now every hour 100 keys are released. This is actually a pretty decent game for fans of the genre. It has been free before so many of you might already have it in your library. This post is for those of you who are new or who missed out on a key last time. Has been on for a while now so I think this could be classed as a long running deal.
If you do not get a key immediately have a bit of patience and try back every hour. Best to try it on the hour I think.
This game is part of the Earth 2150 Trilogy:

How to get the keys:
The same procedure as with the other deals:

Scroll down and find the keys
Click to get Steam key
Redeem key on your Steam account.
Enjoy.
